Plus Model 062 Lanz BULLDOG 35 HP, caterpillar tractor

The M-1 or Caterpillar D6 or Sixty is an American tracked tractor from the interwar period and World War II. The vehicle was powered by a single 4-cylinder engine, which allowed it to reach speeds of 3.2-4.7 km / h. The power transmission was provided by a 3-speed gearbox. In 1925, two American companies producing tractors and agricultural machinery - Holt Manufacturing Company and Best Tractor Company - merged into today's Caterpillar. The second company (Best Tractor Com.) Transferred the production of its existing tractors to a new economic entity, and the existing Best Sixty tractor received the Caterpillar D6 designation. The Best Sixty tractor was presented for the first time in 1919. The vehicle gained recognition relatively quickly thanks to the ability to drive even in very difficult terrain, high reliability and durability of the entire structure. It was used on the civilian market for various types of field and road works, and during World War II it was used by engineering and sapper units of the US armed forces.
